It is reported " by 2015, PM10 and PM2.5 density drops by 15% compared with 2010 in the air of Beijing, PM2.5 density be dropped to 60 micrograms per cubic meter. " Recently, Beijing Municipal Government holds the special topic to know, " working scheme of atmospheric pollution control of 2012-2020 year of Beijing " (hereafter referred to as " working scheme ") Passed in principle, " working scheme " proposes the management goal of Beijing PM2.5 for the first time, and provide concrete measure of eight big classes of managing air pollution. Among them stipulate, meet and pollute the weather again, Party and government offices and public institution at city level park and drive some motor vehicles.

For causing the reason that PM2.5 pollutes, Beijing Vice Mayor's flood crest has been analyzed publicly during city two Conferences: PM2.5 of Beijing, about over 22% is discharged by the motor vehicle to cause; About 17% burn, produce coal, including boiler heat and old the intersection of household and perimeter distribute the burning of the coal; About 16% are the wind-borne dust constructing and bringing; And 24.5% are the influence that the peripheral province and city bring. For this reason, " working scheme " is on the basis of " air of Beijing cleans the action plan ", have further proposed controlling eight major measures such as monitoring, traffic, fire coal, wind-borne dust, industry, ecology, meeting an urgent need and the public of the air pollution.

Among them, in the coal-fired respect, " working scheme " " twelve five " put forward in " the air of Beijing cleans the action plan " The total amount of consumption of coal of the whole city of the end is cut down to the foundations of 20 million tons, has increased the goal in 2020 years. The scheme proposes, by 2020, the total amount of consumption of coal of the whole city is limited to 10 million tons, than " eleven five " The end subdues 62%. In traffic, this city would finish the whole " twelve five " ahead of time in 2013 Eliminate the goals of 400,000 old motor vehicles during this time, but in wind-borne dust, will also popularize the standard of keeping a public place clean of Olympic period.

In addition, have also set up" meets an urgent need " in " working scheme " Content of the respect. Meet and pollute the weather again, Beijing will suspend homework of cubic metre of earth and stone of construction site and dregs to transport, some enterprises stop production, drop in production, Party and government offices and public institution at city level park and drive some motor vehicles.

Management goal

The density dropped by 15% to manage PM2.5 and have in index 5 for the first time

The level of pollution of the particulate matter in Beijing is still very high. According to monitoring data of the Environmental Protection Agency, 2010, Beijing PM10 (inhalable particles) in the atmosphere The average annual density is 121 micrograms / cubic meter, exceed the current national standard (100 micrograms / cubic meter) 21%. And show according to the research monitoring result since 2008, the average annual density of Beijing PM2.5 is about 70 micrograms / cubic meter, go beyond person who limit in the " the national the intersection of air and quality criteria " that will issue soon ' 35 micrograms / cubic meter) Nearly one time. Even influence very small Miyun Reservoir in the artificial activity, PM2.5 average annual density is among 45 to 50 micrograms per cubic meter.

As to this, " working scheme " is proposed: By 2015, PM10 and PM2.5 density drops by 15% compared with 2010 respectively in air of this city, PM10 will be basically dropped to 100 micrograms / cubic meter, PM2.5 density dropped to 60 micrograms / cubic meter; By 2020, the main pollutant density will drop by 30% compared with 2010 in air of this city, PM10 density reach 80 micrograms / cubic meter, PM2.5 reaches 50 micrograms / cubic meter, the density of sulfur dioxide is dropped to under 20 micrograms / cubic meter, ozone exceeds standard the number is reduced by 30% hour. 2020 years later, this city will also make great efforts to make air quality continue improving. According to managing the process of the atmospheric environment at present, the air quality in this city will reach the national standard in 2030.

Goal and the public expect that there is disparity

"By 2015, the average annual density of PM10 and PM2.5 drops by 15%, by 2030, drop by 30%, in view of range of emission reduction, efforts is still greater. " The public and environmental research center director Ma Jun in Beijing say, but even like this, the goal values of PM10 and PM2.5 still exceeded standard by a wide margin in 2020 when confirm at present, and this standard (" surrounding air quality criteria " that is revising) World Health Organization (WHO) The lowest goal value in three transition periods that put forward, there is disparity between this and public expectation.

Ma Jun says, some other countries and cities in the world, such as London of Britain, the administration of its particulate matter has gone through the long course too. But the pollution of China is fast-growth, so the public expects to reflect China's speed in managing. He says, compared with some developed countries, it is late coming that the atmosphere of China is controlled, but late coming to there is a late coming advantage, can draw forefathers' effective experience, can improve faster.

"There are goals in Beijing now, can find out, the efforts managed is being strengthened correspondingly too. " Ma Jun says, in eight major measures that are put forward newly, stricter before comparing, the step managed is being accelerated too, but still some difficult points are existing. For instance, control " exhaust emission reduction of motor vehicle " of the respect in the traffic ,In managing in the area " The joint defence is united and accused of " The difficulty is very great.

Manage eight major measures of air pollution

Monitoring

" day eyes " Atmosphere of telemetering measurement

This city will monitor PM2.5 in an all-round way this year. Set up PM2.5, monitor station, make it reach 35 piece about outside not to monitor the intersection of station and total number, this city will also set up the remote sensing monitoring system of satellites, will form the ground and air quality monitoring net combined in the sky.

Fire coal

The volume of consumption subdues 62%

In the following several years, clean energy such as the natural gas and electricity will occupy the leading position of energy market in this city. The coal-fired proportion in the whole city will be controlled below 10% by 2020, the total amount of consumption of coal of the whole city will be limited to 10 million tons, than " eleven five " The end subdues 62%.

Meet an urgent need

Some buses park and drive

This city will improve air quality and pollute the emergency preplan on day again. Meet and pollute the weather again, this city will suspend homework of cubic metre of earth and stone of construction site and dregs to transport, some enterprises stop production, drop in production, Party and government offices and public institution at city level park and drive some motor vehicles.

The public

Manage pollution to participate in together

Citizen need, change life style, in getting green to go out and energy-concerving and environment-protective take the lead in hanging down Fan, fulfil green life and consumption mode. The enterprises and institutions should implement the subject responsibility of the reduction of pollutant discharge, adopt the technology of pollution control actively, control disposal of pollutants.

Traffic

Eliminate the old car ahead of time

This city would finish ahead of time in 2013 " Twelve five " Eliminate the goals of 400,000 old motor vehicles. Eliminate 300,000 by force by 2015? ? The standard old motor vehicle of what has been bought 001 years ago country, eliminate the old motor vehicle under 900,000 country standards by 2020. This city raise getting green to go out proportion by a wide margin also, the duke of central urban district will reach 50% handing over the conduct proportion in 2015.

Industry

Refuse the high contaminated industry

This city will forbid newly building, extending oil refining, petrochemical industry, cement, steel, casting, building materials,etc. high pollution, highly energy-consuming industry in the future. The scale, the above industrial project, must be entered in the industrial park or industrial base. 2015 years ago, enterprises such as the waterproof roll material of 1200 of pitch, glass, pottery,etc. will withdraw from this city, the eastern chemical plant will stop production and withdraw. By 2020, the operational cement plants of the whole city all close down, suspend operations and withdraw.

Wind-borne dust

Popularize the standard of keeping a public place clean of the Olympic Games

The intersection of this city and construction site accuse of the intersection of cubic metre of earth and stone and the intersection of homework and area severely, reduce, uncover the homework. The road will keep a public place clean according to the standard of keeping a public place clean during the course of the Olympic Games, all roads implement the homework of mechanized dust absorption, main main road and the intersection of construction site and perimeter implement, erode, keep a public place clean homework, guarantee no dust will arise in the road. This city will check severely the dregs car is transported, stop the dregs dropped.

Ecology

Improve environmental self-purification strength

This city plan increases the 66666.667 hectares of forest land of plain in 5 years, the afforesting rate of the forest is up to 57% by 2015. Increase 66666.667 hectares of forest land by 2020, forest coverage rate of plain is up to 35%, obviously increase environmental self-purification ability. This city also plans to increase 750 hectares of coverage of water area by 2015, increase 2000 hectares of water areas newly by 2020, expand environmental capacity.

Difficult point

Coal-fired overall control will be a difficult point

"Under the situation generally upward in total amount in national coal-fired consumption, but Beijing proposes cutting down the index, I think, this has daring and resolution very much. " China environmental FaHe Chai, Vice President of research institute, say for eliminate old car from, refuse high enterprise with heavy pollution, popularize Olympic Games, keep a public place clean standard,etc., coal-fired total amount is actually more difficult to cut down.

As to Beijing " Twelve five " The total amount of coal-fired consumption of the end is cut down from present 26 million tons to the goal of 20 million tons, Chai FaHe says that very confident. FaHe Chai say he participate in the intersection of Beijing and " the twelve 5 " Energy development plan prove, five year every these how to get to true, have already done abundant preparation in Beijing.

"But could cut down 10 million tons of fire coal more by 2020, it depends on the planning in the future. " Chai FaHe says, utilizes clean energy and the adjustment of jointing department and vast rural area energy structure in urban and rural areas will be the important position to cut down coal-fired quantity. If these problems are all solved, the goal of 2020 may be realized, but demand the efforts greatly too.
